40A 30mA 2 Pole RCD (Type A) – Wylex | Wylex (WRDS40/2)

Description

Wylex
40 Amp 30mA 2 Pole RCD (Type A) RCD’s Residual Current Device Offers Protection against Electric Shock
An RCD provides protection against earth faults occurring in equipment and reduces the effects of electric shock on human beings and thus saves lives.
An RCD measures the current flowing in the live and neutral cables and if there is an imbalance, that is current flowing to earth above the RCD sensitivity, the RCD will trip and cut off the supply

• The operating dolly may be locked in either the ON or OFF position without affecting the ability of the trip mechanism to operate, i.e. the RCD is ‘trip-free’. It is not possible to hold the contacts closed when a fault condition exists.
• When in the OFF position a contact gap of 4 mm is present, enabling Wylex RCDs to be used as isolating switches where appropriate.
